I got a call from a customer last week, that they was unable to update there boot image in MDT after upgrading Windows ADK from 1803 to 1809 – error is “Unable to open the specified WIM file.” It is not the first time i get this question – so now it is time to write a short blog post on how to fix it.
The first question is – have you also installed ” Windows PE add-on for the ADK” ??
From Windows ADK 1809 Microsoft has created the ADK into two installers – the ADK and the ADK WinPE add-on – download the WinPE Add-on here and install it on the same box as the ADK.
Now you are able to update your boot image again.
Happy deployment !
Here is the details of the error :
=== Making sure the deployment share has the latest x86 tools ===
== Processing LiteTouchPE (x86) boot image ===
Building requested boot image profile.

Hi!
Bye!
Perfect,
I installed the ADK WinPE and really solved my issue…
Thanks!
Thank you! This was driving me crazy!
Thank you! ADK WinPE solved my issue!
thank you, I forgot this step
thanks
it was right on time with the first result in google
It does not work for me! I install all packages and the Deployment was working for a couple of days. I updated a driver package and start to receive this error. Uninstall ADK and MDT reboot install again, clean up the old LiteTouch .wim file from Boot folder! Start Update Workbench and it takes about 8 hours and failed with the same error. Is there any step I miss? Appreciate any help.
Damn, thanks for this. Been doing this for years, no need to read any special download notes … who would have guessed they’d have suddenly split the ADK up!
You saved my rear. I reloaded my machine and after installing MDT and ADK, everything broke. Thank you for putting my mind at ease with simple instructions.
Thanks! Intalling the WinPE worked for me.
import-mdtoperatingsystem : Unable to get information for WIM file E:\\Sources\Install.wim. (although its there)
This is what i get while importing 1909 even though i have updated to MDT – 8456 and ADK and ADK-WPE 10.1.18362.1 .
I am getting a similar error but it says data is invalid instead of cannot find system files.
👍Thanks worked a treat.
Worked perfectly! Thank you
